Tidyrepo.com claims to be a curated list of “the best and most reliable WordPress plugins”. I’ve used almost all of these plugins and can attest to the fact that yes, they got it right. The only thing I would say is that some of their plugins (Gravity Forms, WP DB Migrate Pro) are paid plugins and some are free. I would have liked the list to be all free plugins and then have a separate list for the best paid plugins out there.
